Notes:

- Is each fact referenced with an appropriate, reliable reference?

 The third paragraph, which discusses gives some examples of fields where anomalous diffusion could be applied, does not cite any sources.

- Is everything in the article relevant to the article topic? Is there anything that distracted you?

 The part about anomalous diffusion frameworks in the statistical physics community was not explained very well.

- Is the article neutral? Are there any claims, or frames, that appear heavily biased toward a particular position?

 I did not detect any biases in the article.

- Where does the information come from? Are these neutral sources? If biased, is that bias noted?

 The sources are all from peer-reviewed journals and do not appear to be biased.

- Are there viewpoints that are overrepresented, or underrepresented?

 The article includes examples from a variety of fields, but could use to expand on these examples.

- Check a few citations. Do the links work? Is there any close paraphrasing or plagiarism in the article?

 The links appear to work. I didn't notice any plagiarism based on the sources that I checked.

- Is any information out of date? Is anything missing that could be added?

 More examples of anomalous diffusion could be added, and current examples could be explained in more detail. There is no reference to anomalous diffusion in the atmosphere.

- What new paragraph or section would you add if you could?

 I would add an explanation of the relevance to pollutant cloud growth in the atmosphere.

- How might you re-arrange the article to make it easier to understand?

 Examples are given in both the first and second section of the article. Perhaps all examples could be moved under the subheading "types (or examples) of anomalous diffusion".

- How many equations are included in the article? Too many? Too few? Do they over-whelm the article? How might you make the article more achievable for a first time reader?

 The equations are useful for understanding the difference between linear and nonlinear diffusion.

- How does the way the topic is discussed on Wikipedia compare to how we've discussed this topic in class?

 The explanation of non-linear diffusion is similar. Perhaps the terms "scale-dependent diffusion" or "non-Fickian diffusion" could be added.

Anomalous diffusion is also seen in plume growth in the atmosphere. As a plume grows, it is exposed to larger-scale motions in the atmosphere, which produce greater mixing and increase the rate at which the plume expands. Because the scale of motions in the atmosphere is not limited, as in rivers or the subsurface, the plume continues to experience larger and larger motions, and its diffusivity grows non-linearly.[1]
